To all whom it may concern.-

Be it known that I, AARON WARFIELD, of the city of Toronto, in the county of York and Province of Ontario, Dominion of Canada, a citizen of the United States of America, have invented a new and useful Cement Railway-Tie and Rail-Fastening, of which the following is a specification.

My invention relates to a railway tie, cast or formed from cement, and having formed therewith, metal fastening plates, adapted to receive means for adjustably attaching the rails to the tie. The combination of the fastening plates besides forming a base for the rails, also acts as a strengthening means for the tie, especially cross-wise. Besides the fastening plates, I cast in the tie a series of rods, in parallel and longitudinal positions, to thoroughly reinforce the tie lengthwise.

The object of casting or forming the tie from cement, is to provide for uniformity in size and weight, also to lengthen the life of the tie, as the cement is impervious to dampness, and will not be subject to decay therefrom. Heat will also have no effect on the cement to cause dry rot.

The fastening means provided in combination with the fastening plates, are adapted to attach and allow the rails to be detached as often as required, in a manner that they will in no way affect or destroy the tie. The fastening means are also of such a nature, that rails may be set at different gages, also for rails of different widths, especially those formed with wider and narrower bases, with out in any way altering the tie or fastening plates. The fastening means are so constructed that adjustments may be quickly and minutely made, and very rigidly hold the rail to the tie, and provide against misplacement. The fastening means may also be adapted to any railway tie, as well as for the purpose herein described and illustrated. I attain these objects by my invention as illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a section of track; Fig. 2 is a perspective view of one of the ties Fig. 3 is a cross sectional view on lines a-a Fig. 2; Fig. 4 is a longitudinal sectional view on lines b-b Fig. 2; Fig. 5 is an end view of one of the ties with a section of rail and fastening means; Fig. 6 is a detail view of a section of the end of a tie showing a section of a rail and fastening means; Fig. 7 is a perspective view of one of the fastening plates, Fig. 8 is a side elevation of one of the fastening dogs; Fig. 9 is a perspective view of one of the locking keys, Fig. 10 is a perspective View of one of the fastening dogs; Fig. 11 is a perspective view of an alternative form of locking key; Fig. 12 is a perspective view of a section of a tie and rail with an alternative form of fastening means; Fig. 13 is a longitudinal sectional view on lines c-(; Fig. 12.

Like characters refer to like parts throughout the drawings and specifications.

a designates the tie, formed from cement, the regulation length and width, preferably rectangular in cross section. Cast in the tie longitudinally and parallel, are a series of bars I), for the purpose of reinforcing the tie lengthwise, also cast in the tie are fastening plates c-c, one at each end flush with the top face. The fastening plates 0 are formed with a top and two sides cc, the sides endmg with an out turned right angle flange 0 whereby they form an anchor to set in the cement to prevent misplacement or withdrawal. The fastening plates cc also act as a strengthening means, to strengthen the tie crosswise.

d designates the fastening dogs by which the rails may be fastened to the tie, and e designates the locking key by which the dogs are adjustably fastened to the fastemng plate 0.

Formed. through the top face of the fastening plates 0 are a series of openings, arranged in duplicates, the openings 1--1 bemg for the purpose of receiving the lugs d of the fastening dogs (1, and the openings 22 bemg for the purpose of receiving the wedge shaped heads 6 of the locking keys 6.

The fastening dogs (1 are formed with a socket (1 adapted to receive the circular end 6 of the locking key a. Formed through the sides of the dog 6 are a series of openings d through which may be passed a cotter-pm or plug, to aid in holding the locking key in rigid engagement with the fastening dog.

Formed in the tie a, referably when being cast, are a series of poo ets a. The pockets are situated immediately beneath the openings 1 and 2 in the fastening plates 0 and are for the purpose of admitting the flanges and heads of the fastening dogs and locking keys respectively, when being adjusted and fastened to the fastening plates.

f designates a tie-bar, for the purpose of coupling the two fastening plates 0 together and maintain them against lateral displacement. The ends of the tie are riveted to the adjacent edges of the fastening plates, and are embedded in the cement with the fastening plates.

In fastening the rail g to the tie, a fastening dog dis arranged on each side of the rail, with the head (i engaging over the base flange g of the rail. The dog at engages and is fastened in the fastening plate a, by inserting the lug cl into the cross-slot 3 forming part of the opening 1, and is then forced forward into the opening 1 where it is prevented from being forced upward by projections 61 one extending laterally from each side of the lug d, and adapted to engage under the edges of the fastening plate.

To prevent displacement of the dogs 65 and to lock them in position, I provide the locking key a, formed with a circular end e adapted to engage in the socket d in the dog d. The opposite end of the locking key is formed with a wedge shaped head e, having a series of notches formed along its outer edge.

To lock the dog (1 in its adjusted position in the fastening plate, the end 6 of the locking key is inserted into the socket (Z in the dog, and the wedge sha ed head 0 is inserted into the slot 2 in the fastening plate and is forced or pounded downward until one of the notches e springs under the edge of the fastening plate 0, by which it will be firmly held and may not be removed unless by the aid of a lever or wedge which may be inserted un der the center p art of the locking key to force it up and spring it out of engagement with the edge of the fastening plate. The edge of the slot against which the notches engage is chamfered so that it may more readily engage in the notches. It will be understood that where a rail with a very narrow base flange is being fastened, the wedge shaped head will be forced farther downward, and in the opposite case where a very wide base flange is in use the wedge shaped head will not enter into the opening as far. By this means of fastening it will be seen, a very perfect adjustment is provided for without in any way affecting the tie, or the fastening late formed therewith.

Slight modifications may be made to the fastening plates by eliminating the sides and anchor flanges to adapt them to be fixed to I wooden ties, whereby the rails may be fastened to the tie as herein described, The fastening dogs and locking keys as herein described, are also adapted to be used in combination with metal railway ties for fastening the rails to the same.

The slots 1 in which the lugs of the locking dogs engage are sufficiently long to permit of the lateral adjustments on each side of the rail.

In Figs. 11; 12 and 13, I have shown an alternative form of fastening for the rail. The tie in this form is identical with the former, also fastening plates 11 are cast therein. In the alternative form, I eliminate the locking dog, and instead thereof I substitute a locking key 12 that fulfils the dual purposes, and the locking plate is only pro vided with one set of openings 13, in which engages the locking key. The locking key 1.2 is formed with a clamping 1-1 at one end, adapted to engage over the base flange m of the rail n, and under the edge of the fastening plate. The opposite end of the locking key 1.2 is formed with a wedge shaped head 15, and formed along its outer edge are a series of notches 16, adapted to engage with the chamfered edge 17 of the fastening plate. To fasten the rail to the tie, the locking key is inserted into the opening 13 in the fastening plate, and is forced forward until the jaws 1 1 engage over the flanges m of the rail 7%, and under the edge of the fastening plate 11, the head 15 of the locking key is then driven down into the slot 13, until one of the notches 16 engages with the chamfered edge 17 of the fastening plate, by which it will be held firmly against lateral movement or from rising.

In Fig. 8 I have shown a slightly modified form of the locking dog. Formed integral with the head (1, is a raised fin 0, adapted to engage against the web of the rail, to act as a further means for engaging with the rail.

ith a railway tie as herein described, I provide means by which a very flat and uniform railway bed may be constructed, and also a tie provided with fastening means by which the rail may be very quickly adjusted, and whereby the frequency of adjustment will have little or no effect as regards destruction.

Slight modifications may be made in the shape and construction of the fastening dogs and locking keys, without deviating from the nature of my invention.

The essential features of my invention lie in the construction of a railway tiefrom cement, the means of reinforcing it lengthwise and crosswise, as well as the means for fastening to a cement body without fear of chipping or working loose by yibration.

What I claim as new and desire to secure by Letters Patent, is-
